VILLIAM LA MAR, OF PLEASANTVILLE, IOVA.

GATE.

SPECIFICATION forming part' of Letters Patent No. 395,336, dated January 1, 1889.

Application tiled August 7,1888. Serial No. 282,169. (No model.)

To all whom-it may concern:

Be it known that I, VILLIAM LA MAR, a citizen of the United States of' America, and a resident ot Pleasantville, in the county of Marion and State of Iowa, have invented a new and useful Improvement in Farm-Gates, of which the following is a specification.

My improvement relates to that class of gates that are mounted upon rollers and moved longitudinally by means of levers that extend at right angles from the gate; and my invention consists in the construction and combination of a compound lever adapted for moving and also locking a gate with a fixed post and a sliding gate, as hereinafter set forth, pointed out in my claim, and illustrated in the accompanying drawing, which is a perspective-view ot' my gate.

A represents a sliding gate of common form. B and B'3 are fixed posts at the rear end of the gate, and C is a fixed post at the front of the gate.

(l are rollers upon bearers fixed to the posts li B2 to support the gate and to facilitate its sliding motion.

f are tracks fixed upon the edges ot' the horizontal' bars of the gate in such positions that they will be engaged by the rollers, which are preferably grooved in their peripheries.

g an elbow-shaped lever pivoted to the post B2 at a point above the top of the gate, andthe end of its long arm connected with the bottom portionV of the front end of the gate by means of a bar, h, pivot-ed to thelever and also to the gate. The short arm of this lever is adapted in form and position to serve as a latch t'or locking the gate when it is closed. V

J is a fulcrum fixed to the top ot' the post B2 to extend horizontally and `to support a lever, 7.x, pivoted to the free end of the fulcrum in such a manner that the lever will extend at right angles across the gate and vi brate vertically.

In is a rod flexibly connected with the lever k and the short arm of the lever g in such a manner that when the lever lc is lifted the short arm of the lever g will go up and its long arm down, and as thislong arm descends it will draw the gate open.

h is an arm fixed to the pivoted end of the lever k, so that after the lever has been lifted and the gate opened and a person has passed through the gateway he can close the gate by lifting the arm and thereby reversing the motions of the levers k and g, as required, to close the gate.

Then the gate is to be opened by a person approaching the side of the gate upon which the posts B and B2 are, th e arm la can readily be pulled downward by means of a rope attached to its free end to lift the lever k and thereby operate the lever g to slide the gate open; and when the gate is thus opened by pulling down. the arm 71 it willleave the lever 7.-. elevated, so that the gate can then be closed by pulling the lever l.' down by' means of a rope attached to its Vfree end.

o" is alocking device in the form of a block or bar fixed on the top of the gate in such a manner that when the gate is closed the short arm of the lever g will come in contact with the end ot' the bar and prevent any longitudinal movement of the gate as long as the lever g remains stationary.

s is a projection on the end of the gate that enters a mortise in the post C and prevents any lateral motion of the gate when closed.

l am aware that an elbow-shaped lever has been pivoted to a post and connected with a sliding gate, and two distinct levers pivoted to the ends of a cross-bar fixed to the top of the post in such a manner that the gate could be thereby moved in reverse ways. I am aware, also, that the top of a gate has been notched to receive a vertically-moving bolt to be thereby locked; but my manner of combining an arm with a single lever pivoted to a fulcrum that extends laterally from a fixed post and connecting it with an elbowshaped lever and a gate to open and close and lock the gate by the operation of the single lever having a fixed arm is novel and advantageous.

I claim as my invention The combination, with a sliding gate having a fixed block, r, on its top, of the bar h, pivoted to the gate, the elbow-lever g, pivoted to bar h, and also to the gate-posu'so as to engage the block r with its short arm when the gate is closed, and an operating-lever, la, connected to its short arm, substantially as` shown and described.
